Abstract: According to the widely established dual-process model, the perirhinal cortex and hippocampus make distinct contributions to recognition memory in the form of familiarity and recollection. These two processes are associated with the curvilinearity and y-intercept of the ROC-curves, respectively. The evidence that hippocampal lesions affect the y-intercept more than the curvilinearity seems to support this view. Here, we argue that quantitative differences between generic memory modules are sufficient to account for this result. Thus, two qualitatively different memory systems are not required. Although similarities to single-process accounts exist, our model generates realistic ROC-curves based on distinct mechanisms.
